Plextor PX-M2 Series 256GB SATA 6G Solid State Drive Review

TweakTown Rating: 89%Manufacturer: Plextor



We would like to thank the following companies for supplying and supporting us with our test system hardware and equipment: AVADirect, GIGABYTE, Cooler Master, LSI, Corsair and Noctua.

In order to achieve the highest levels of performance from your next generation SATA 6G drive, you will need a high performance SATA 6G bus to run the drive on. We choose GIGABYTE's P67A-UD5 since it offers more bandwidth than the Marvell SATA 6G implementation found on many X58 motherboards. Another option would be to use a high performance 6Gb/s RAID controller like the LSI 9260-8i.


Plextor was first to market with their new next generation SATA 6G SSD (the Crucial C300 was a previous generation), but they are the last to get a product in our hands. Now that we have the whole gamut of next gen controllers at our disposal, we can compare the PX-M2 to SandForce's SF-2200 and Crucial's m4 products and get a clear representation of where the Plextor drive sits.


ATTO Baseline Performance


Version and / or Patch Used: 2.34


ATTO is used by many disk manufacturers to determine the read and write speeds that will be presented to customers.




As expected, we found the Plextor PX-M2 performing at very high levels, but a little off from their quoted speeds. Our measurement showed read speeds of very close to 450MB/s and write speed around 315MB/s. With the drive already being brought to a steady state by the previous reviewer, we couldn't measure out of the box speeds which would have been a little higher than what we measured here.
